Mr. Joseph Lipka <br />Forward Landfill <br />May 21, 2018 <br />Page 3 <br />Safety and Health (Cal-OSHA), and the American Conference of Governmental Industrial <br />Hygienists (ACGIH) for airborne asbestos fibers range from 0.1 to 2.0 f/cc for those fibers <br />greater than 5.0 microns in length. The Environmental Protection Agency has published <br />environmental clearance levels for asbestos fibers at 0.01 to 0.02 f/cc. <br />As mentioned previously, asbestos fibers were not detected in any of the samples. The detection <br />limits reported by the laboratory for the locations sampled during April 2018 are several orders <br />of magnitude below applicable published occupational and environmental exposure or clearance <br />criteria. No differences were observed between the upwind and downwind monitoring locations <br />indicating that the disposal operations did not increase the background concentrations of <br />asbestos fibers in the vicinity of the site. <br />Thank you for the opportunity to provide the requested services. Please call if you have any <br />questions. <br />Sincerely, <br /> <br />FIELD SOLUTIONS, INC. <br /> <br />PATRICK LACEY, CIH <br />FIELD SERVICES MANAGER <br /> <br />Attachments: Figure 1 – Ambient Asbestos Air Monitoring Locations <br />Appendix A– Air Monitoring Plan, Forward Landfill <br />Appendix B – Laboratory Reports and Chain of Custody Record <br /> <br />
